AssemblyInformationalVersion should accept any string

AssemblyInformationalVersion is parsed as a Version and it should accept arbitrary strings. In IKVM's VersionInfo.cs:

if (informationalVersion != null)
{
Version productver = new Version(informationalVersion);
productVersionMajor = productver.Major;
productVersionMinor = productver.Minor;
productVersionBuild = productver.Build;
productVersionRevision = productver.Revision;
}

This attribute accepts arbitrary strings and allows developers to set unconstrained information about the build. An example source code in C# is attached that utilizes all three version attributes (assembly, file and informational version), it compiles fine. The same Java source, compiled with IKVM, crashes with an error:

System.ArgumentException: Version string portion was too short or too long.
